It worked in the demo.
Your app worked — until real users showed up. Checkout crashes, retry storms, sessions that drop mid-signup. Kitsoki's bugfix agent reproduces the bug on record, ships the smallest fix that passes, and hands you a green PR — no fix ships without a failing reproduction first.
It is not done. It just says it is.
A generic coding agent patches the symptom, declares victory, and moves on — no proof, no repro, no memory of the last five times it said the same thing. That's the pattern behind the 66% of developers who call AI-assisted fixes "almost right" and the 23% rise in incidents per PR since agents started shipping code unsupervised.
Kitsoki's bugfix agent runs a different loop: reproduce the bug on record, fix the smallest thing that passes, prove it against the same reproduction — before anything ships. No fix without a failing test first.
No repro, no fix.
Every stage is inspectable and every fix is proven against a reproduction captured before the first line changes — the gate the rest of the market skips.
Triage
Logs, traces, and reports are pulled into one ranked list — the checkout crash and the retry storm are the same incident, not five separate tickets.
Reproduce
The bug is reproduced deterministically before anyone touches code. If it can’t be reproduced, it doesn’t move to fix — that’s the gate, not a suggestion.
Fix
A scoped diff, not a rewrite. Kitsoki proposes the minimal change that makes the reproduction pass — nothing your team has to untangle later.
Prove
The fix is verified against the same failing reproduction, CI is watched to green, and the PR stays live through review comments until you merge it.
Receipts, not promises.
Every engagement ends with evidence your team can check — not a chat log claiming the work is done.
The checkout crash, reproduced on record before the fix — and re-run against the same case after.
A live PR that stays attached through review comments and CI — you review and merge, nothing more.
A report your whole team can read — reproduction, root cause, fix, and the security pass, in plain language.
Kitsoki. Debugged, with receipts.
